Bush and Rumsfeld's almost other-wordly incompetence is dissected here by Ray McGovern. Key graph:
As was the case in Vietnam, the Iraq war is being run by civilians innocent of military experience and disdainful of advice from the colonels and majors who know which end is up. Aping the president’s practice of surrounding himself with sycophants, Rumsfeld has promoted a coterie of yes-men to top military ranks—men who “kiss up and kick down,” in the words of former Assistant Secretary of State Carl Ford, describing UN-nominee John Bolton’s modus operandi at the State Department. So when the president assures us, as he did yesterday, that he will be guided by the “sober judgment of our military leaders” he is referring to the castrati.
This is the "thinking" that has led us into disaster. This is one of the consequences of the 2000 coup d'etat that illegally put Bush in power. This is part of the price we're paying.
